Description

Technical field

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plastic directional column of a modular construction, in particular for demarcation of roads, motorways, for use as a directional column on a crash barrier and the like.

BACKGROUND OF THE INVENTION

The current directional columns for the boundaries of roads, highways, crash barriers, etc. are usually made up of one body, without essential functional features. In order to meet the standards for road, road, highway, etc. bounding, these posts must be color-coded in their central part and include other elements such as colored foil cuffs or colored foil cuffs with reflectors.

Directional posts are also known, the body of which is composed of a plurality of parts, butt-welded together or by longitudinal weld. Assembly of such posts is difficult because the individual parts of the post body do not have leading shapes. This increases the laboriousness of assembling them, ie aligning the individual parts of the column body with respect to each other and subsequently welding along the entire circumference of the parts to be welded.

The disadvantages of the above-described directional columns are their uniqueness, mutual non-adaptability and unmistakability of individual parts. If any part of the column body is damaged, for example after being hit by a vehicle, the entire column body must be replaced, which is economically disadvantageous. Also, providing color coding for the central body portion of the post that is required increases the cost of manufacturing.

From the Swiss application, a post is known which comprises a one-piece base body. A protective cover or sleeve is attached to this body to ensure the distinctive and functional operation of the post, on top of which the signaling elements, i.e., colored foil cuffs or colored foil cuffs with reflectors, are attached. The need to add a cover or protective sleeve to the base body substantially increases the cost of ensuring the post is functioning properly, otherwise the post is inoperative. In addition, the protective cover or housing must be of a material which allows good adhesion of the signaling element. Furthermore, as stated in the application, the housing or protective cover must be partially covered with reflective paint, which again entails increased production costs. Also in this solution, if the base carrier is damaged, the column must be replaced completely.

A common disadvantage of all the columns described above, apart from the disadvantages already described, is that their central part, on which the signaling element is located, needs to be color-coded in a separate operation. As a signaling element, a colored foil cuff, or a colored foil cuff with reflectors, which is most often damaged in the event of a vehicle impact or also due to weathering, is generally used. Damage to the foil cuffs may result in loss of orientation for drivers,

This may cause undesirable traffic accidents.

SUMMARY OF THE INVENTION

These drawbacks of the present directional posts are largely overcome by the plastic directional post of the modular construction according to the invention, the body of which comprises at least three parts, the lower support part being anchored to, for example, a foot or a barrier. The principle of the solution consists in that an inner insertion shape is formed on the opposite side of the anchored part of the lower support part, into which the first outer insertion shape of the middle part is introduced at one end. A second outer insertion shape is formed at the other end of the central portion into which the upper portion is introduced through the inner insertion shape.

In order to ensure easy manufacturing of the individual parts to be joined in one operation, the outer dimensions of the insertion shapes of the middle part correspond to the internal dimensions of the insertion shapes of the lower part and the upper part, and the cross sections of the outer insertion shapes of both the middle part and identical in shape to the outer cross-sections of the lower part, the middle part and the upper part. To ensure that the middle part does not have to differ in color from the lower support part and the upper part after the fabrication, as required by standards, the whole is made of a different color.

The most commonly used embodiment of a plastic directional post is a solution with parts having the shape of an isosceles triangle, the corners of the triangle being rounded. However, the assembled post body can also be made in a tubular or oval profile.

It is advantageous if the outer insertion shapes of the central part have closed faces, as this will strengthen the entire composite column body.

Embossments are formed on the walls of the central part in which reflectors of various geometric shapes are attached - for example, rectangular, circular, etc. If the cross-section of the column body parts is designed in the shape of an isosceles triangle, embossments for attaching reflectors are formed on the isosceles. Refitting the reflectors to the central part is done on the lock, which is part of the reflectors and is of the same material.

However, the connection method by simply inserting the insertion shapes of the individual pillar body parts into each other may not meet the requirements of all standards and users and therefore the pillar body parts are secured against ejection. The parts can be secured against ejection in a detachable or non-detachable manner.

One preferred embodiment of the releasable securing of the column body parts against sliding is a lock provided to the lock, which is secured by forming protrusions on the outer insertion shapes of the middle portion and by making holes in the inner insertion shapes of the lower support and upper portions.

-2GB 278464 B6

Another method of releasably securing pillar body parts is by means of removable rivets and pins which are inserted into common openings formed on the outer insertion shapes of the middle portion and the inner insertion shapes of the upper portion and the lower portion.

The releasable locking may also be provided by overlapping the outer or inner insertion shape of the parts to be joined. Typically, an overlap will be provided to fit the outer insertion shapes of the middle portion of the column body.

Some standards, as well as the requirements of some users, will require that the directional column body be rigidly formed and cannot be disassembled. To meet this requirement, the column body parts that are inserted into each other by their insertion shapes and thus axially aligned are only fixed by spot welding.

By providing a post body according to the present invention, advantages are obtained that can be divided into advantages arising at the directional post manufacturer and at the consumer.

Advantages of the manufacturer are that by suitable replacement (combination) of individual body parts. The post can be easily, quickly and without high production costs adjusted to the production of individual body parts to the requirements of different types of posts and standards. This will reduce mold production costs and hence the cost of the directional column.

The user benefits from simple replaceability of individual parts, especially during repair and maintenance, reducing operating costs for post restoration. It also reduces the transport effort when replacing defective parts, as the entire body of the post does not need to be transported, but only the damaged part.

A further advantage of the solution is that the central part of the post body is colored throughout the mass and therefore does not need to be applied to colored foil cuffs or colored foil cuffs with reflectors. As a result, they cannot be damaged as a result of weather conditions and therefore increase road safety. The middle part is colored according to the user's requirements and the relevant standard.

By attaching the reflectors to the central portion of the column body by means of a lock that is integral with the reflectors, it prevents the reflective surface of these reflectors from being reduced by other detachable attachment means.

DETAILED DESCRIPTION OF THE INVENTION

The body of the pillar of the triangular profile 1 according to FIGS. 1 and 2 consists of an upper part 2, a middle part -3 and a lower support part 7. The lower support part 7 is anchored by a part 18 to a foot 19 in the ground or to a barrier 20, 10 and 11. The lower support member 7 may be. depending on safety requirements, made of a flexible or shattering material. The middle guide 2 is slid onto the inner guide shape 6 of the lower support member 7 by the first outer guide shape 5. The inner guide shape 6, the upper member 2, which is closed from the other side, is slid onto the second outer guide shape 5 of the middle member 3. The central part 3 with the insertion shapes 5, ⁵¹ is differently colored from the lower support part 7 and the upper part 2 throughout the entire mass - for example in black. The insertion shapes of the central part 2 are made with closed faces 16. On the central part 2 / as shown in FIG. 3, two embossments 15 are formed on the walls 21, one in the direction of travel and the other in the opposite direction. The recesses are fixed reflex reflector 4. Attaching the reflectors 4 to the housing 2 is provided a lock 17 (FIG. 6) which is part of the reflectors and of the same material. · Interconnection of the upper part 2, the middle part 2 ^and the lower bearing part 7 in this case, they are inserted into each other in the insertion shapes, without further securing against extension.

According to Figs. 4 and 5, where the same reference numerals are used for the same elements as in Figs. 1 and 2, examples are provided of securing the central part 2 with the lower support part 7 by means of a lock 2 (Fig. 4) and removable rivet 12; pin 13 (FIG. 5).

The lock according to FIG. 4 is formed by a projection 9 formed on the first outer guide shape 5 of the middle part 2 / ^{and an} opening 10 in the inner guide wall 6 of the lower support part 7. For easy insertion of the first outer guide shape 5 of the middle part 2 into the inner shape 6 the lower support 2 is chamfered on the inner shape 6 of the lower support 2.

The connection by means of the removable rivet 12 and the pin 13 according to FIG. 5 is carried out in such a way that in the insertion shapes of the middle part 2 and the lower support part 2 are formed holes 14 into which the rivets 12 and the pin 13 are inserted.

In the same manner as in FIGS. 4 and 5, other parts of the column body can be secured against ejection.

It will be understood that the various combinations shown in the previous examples may be used to secure the individual parts of the column body against ejection, depending on how the insertion shapes are made on the individual parts, as shown in Figures 7 to 9.

However, the basic provisions and the connection of the individual parts of the column body will always be made by sliding them together over the insertion shapes.
